Motorola's PPC road map lists the G5 as having: -Extensible architecture -New pipeline -New bus topology -64 and 32-bit memory addressing, -0.10-micron SOI -2GHz+ The chip is on schedule for an early 2002 release date. Apple currently has several chips in its labs. They're running on UMA2 motherboards with frontside buses set to 200MHz DDR (400MHz). Using current 0.18-micron fabrication methods, the chip runs stable at 1.3GHz! I'll fill you know more this evening, but I have to go.
